DESCRIPTION

The DAC7632 is a 16-bit, dual channel, voltage output,

Digital-to-Analog Converter (DAC) which provides 15-bit

monotonic performance over the specified temperature range.

The device accepts 24-bit serial input data, has doublebuffered

DAC input logic (allowing simultaneous update of

both DACs), and provides a serial data output for daisychaining

multiple devices. A programmable asynchronous

reset clears all registers to a mid-scale code of 8000H or to

a zero-scale code of 0000H. The DAC7632 can operate from

a single +5V supply or from +5V and –5V supplies, providing

an output range of 0V to +2.5V or –2.5V to +2.5V, respectively.

Low power and small size per DAC make the DAC7632

ideal for industrial process control, data acquisition systems,

and closed-loop servo-control. The DAC7632 is available

in an LQFP-32 package and specified over a –40°C to

+85°C temperature range.
